What lenses can be used with PENTAX digital cameras?

All Pentax lenses ever produced can, however there are restrictions when using lenses other than DA, D FA, FA, FA J series lenses. When using D FA or FA lenses the aperture ring must be set to the A (auto) position. A-series lenses are manual focus only.
